GraphQL is a query language for APIs, and it allows developers to specify exactly what data they want from a server before making a request. However, it’s not always possible to get the full payload or all fields for an object. In this case, you can use the `call` function on a GraphQL schema to make a custom call to the server.

Here’s how you can use `call` to call a post method in a GraphQL API:
Let’s say you have a GraphQL schema that looks like this:
“`python
type Query {
posts: [Post]
}
type Post {
id: ID!
title: String!
content: String!
}
“`
To call a post method, you’ll need to provide the appropriate `Call` object to the `call` function. Here’s an example:
“`javascript
const { Call } = require(‘graphql’);
const call = new Call({
client: yourClient,
mutation: ‘yourMutation’,
variables: { id },
});
call.query({ type: Query, id });
“`
In this example, we’re using the `client` property to create a GraphQL client instance. We’re then defining a `Call` object with our client and mutation. Finally, we’re passing our variables to the `query` method, which will execute the custom post method on the server and return the results as a GraphQL response.
It’s important to note that when calling a post method, you’ll need to pass the appropriate parameters to the server. For example, if the server expects an `id` parameter, you should pass that value along with the rest of your query. You can find more information about what parameters each GraphQL operation takes on the official GraphQL documentation.

Overall, using the `call` function on a GraphQL schema allows you to call custom methods on a server and access the full payload or all fields for an object. It’s a powerful tool that can help you build more flexible and scalable APIs.
